Gravity networks
PVC-U sewerage
For wastewater and stormwater networks, combine the right stiffness class with the usual 6 m format. Fewer connections than shorter bars, and a factory-integrated ring on rubber-ring configurations: fewer operations to carry out in the trench.
Applications
Gravity networks
For drainage, infrastructure and collective networks where stiffness class must match ground constraints.
Assembly
Rubber ring joint
Fast assembly with rubber ring joint to ease installation and support network continuity.
Product choice
SN and DN to validate
SN class, diameter and availability are confirmed according to the project nature and information provided.

PVC-U sewerage: diameters and configurations
Choose the diameter, ring stiffness and socket type for your gravity network. The usual pipe length is 6 m.
| Outside diameter (mm) | Range and classes | Assembly | Usual length |
|---|---|---|---|
| 110 | A10 / A4 / A6 | To specify for your project | 6 m |
| 125 | To specify for your project | To specify for your project | 6 m |
| 160 | A10 / A4 / A6 / CR4 / CR8 | Sealing ring or solvent-weld socket, depending on configuration | 6 m |
| 200 | A10 / A4 / A6 / CR4 / CR8 / SN2 | Sealing ring or solvent-weld socket, depending on configuration | 6 m |
| 250 | A10 / A4 / A6 / CR4 / CR8 / SN2 | Sealing ring or solvent-weld socket, depending on configuration | 6 m |
| 315 | A10 / A6 / CR4 / CR8 | Sealing ring or solvent-weld socket, depending on configuration | 6 m |
| 400 | A10 / A6 / CR4 / CR8 | Sealing ring or solvent-weld socket, depending on configuration | 6 m |
| 500 | A10 / A6 / CR4 / CR8 | Sealing ring or solvent-weld socket, depending on configuration | 6 m |
| 630 | A10 / A6 / CR4 / CR8 | Sealing ring or solvent-weld socket, depending on configuration | 6 m |
Special lengths of 3 m or 4 m are available for selected configurations, on request. A4, A6 and A10 are commercial range names, not pressure ratings. Specify the required SN class in your enquiry.

Assembly operations
The usual 6 m format means fewer pipe-to-pipe connections than 3 m bars on the same straight run. With a factory-integrated ring, your team also avoids fitting a separate ring in the trench.
Right specification
Select the diameter, PN or stiffness class required by your design. Avoid unnecessary oversizing, without compromising the operating requirements of the network.
A complete quotation
Send the route length, quantities and delivery destination. Compare offers on the same diameter, class, joint, usable length and delivery basis.
Illustration: on a straight 120 m run without cuts or fittings, 20 bars of 6 m create 19 pipe-to-pipe joints, compared with 39 for 40 bars of 3 m. That is 20 fewer assembly points; it is not a quantified labour-cost guarantee.
